Jjdancer replied to the thread [SOLVED] Debian 11 not booting with "VirtIO SCSI Single" but works with "VMware PVSCSI".During the next kernel update, dracut will only install the required drivers required for booting up.

Jjdancer replied to the thread 10Gb network adapter.I'm still on Proxmox 8 at home. I do NOT use a transceiver at home. I use a direct-attached cable (DAC) from the NIC to the switch. I believe I the issues with the ConnectX-3 not working with Proxmox 9 may have to do with transceiver...

Jjdancer replied to the thread How to install Proxmox with GRUB?.True this. The Proxmox team may want to consider just using GRUB bootloader exclusively in future versions like how other operating systems do it. And to avoid the issues from systemd-boot to GRUB migrations. Can confirm that the GRUB...

Jjdancer replied to the thread Proxmox Virtual Environment 9.1 available!.No issues on 13th-gen Dells. Time to upgrade the 12th-, 11th-, 10th-gen Dells. On 13th-gen Dells, I have UEFI, Secure Boot, X2APIC, I/OAT DMA enabled. SR-IOV disabled.

Jjdancer replied to the thread How to change to 10Gbps NIC Card option for better migration performance.You'll probably want to use the alternative method created by member PwrBank to overcome the built-in EXSi throttling https://github.com/PwrBank/pve-esxi-import-tools/tree/direct-send More info about this method at...

Jjdancer replied to the thread full mesh network for ceph configuration.Assuming it's a 3-node Ceph cluster with no switch per https://pve.proxmox.com/wiki/Full_Mesh_Network_for_Ceph_Server#Example I put the Ceph public, private, and Corosync network traffic on this network. I also set the datacenter migration...

Jjdancer replied to the thread Ceph Cluster - Slow performance.If this 3-node cluster is never going to be expanded, create a full-mesh broadcast network per https://pve.proxmox.com/wiki/Full_Mesh_Network_for_Ceph_Server#Example and...

Jjdancer replied to the thread How many nodes in a single cluster with Ceph requirement?.I use Dell R630s in production as Proxmox Ceph clusters. These were converted from VMware/vSphere. They all have the same hardware (CPU 2 x 2650v4, Storage SAS 10K, Storage controller HBA330, RAM 512GB, NIC Intel X550 10GbE) running latest...
-
Jjdancer replied to the thread About Proxmox VE & PBS features.May be the issue is with the megaraid_sas driver not able to use "mixed-mode" RAID configuration (RAID and HBA [passthrough]-mode) is the root cause. No idea since I don't use mixed-mode. Still stand with my recommendation on getting a used Dell...
-
Jjdancer replied to the thread Server Suggestions.If it matters, the Dells in production are 13th-generation using Intel Broadwell CPUs. Still firmware supported by Dell. They will eventually get EOL'd by Dell but then again, I have 10th-, 11th-, 12th-gen Dells running Proxmox. I recommend...
-
Jjdancer replied to the thread Proxmox HA cluster with Ceph.Yes, for live migration, manual/HA. Hence, should really have same amount memory across nodes.
-
Jjdancer replied to the thread Server Suggestions.Migrating Dell VMware clusters at work to Proxmox. I just make sure all the hardware is the same (CPU, memory, storage, storage controller, networking, firmware, etc). Swapped out Dell PERCs for Dell HBA330s since ZFS & Ceph don't work with RAID...
-
Jjdancer replied to the thread Proxmox HA cluster with Ceph.Ceph really, really wants homogeneous hardware. Meaning same CPU, memory, networking, storage, storage controller, firmware, etc. While it's true you can run a 3-node cluster, you can only have a 1-node outage. With 5-nodes, can have 2-node...
-
Jjdancer replied to the thread About Proxmox VE & PBS features.I use a Dell PERC H730P in a Proxmox Backup Server (Dell R530). I deleted the virtual disks before converting it to HBA-mode. It's also running the latest firmware from Dell. Proxmox uses the megaraid_sas driver. As for the other Dells in...
-
Jjdancer replied to the thread Proxmox installation failed on Dell R340.The 2 x R530s in question are Proxmox Backup Servers. I did a clean install of PBS 4. It was previously running PBS 3. May want to double check the PERC settings in the BIOS again and confirm it's in HBA mode. Another option it put in a single...
-
Jjdancer replied to the thread Proxmox installation failed on Dell R340.Before converting a RAID controller to HBA mode, you'll want to delete any virtual disks first. If you miss this step, you can do the following: # wipefs -af /dev/sd[x] # sgdisk -Z /dev/sd[x] # wipefs -af /dev/sd[x] Where x is the drive...
-
Jjdancer replied to the thread PVE Best practices and White paper.Like with any deployment, start with a proof-of-concept testbed. As you know, separate OS from data. So, use small drives to mirror the OS. I use ZFS RAID-1. Rest of bigger drives for VMs/data. Strongly suggest to use a IT/HBA-mode storage...
-
Jjdancer replied to the thread Proxmox installation failed on Dell R340.Just get a used Dell HBA330 storage controller. Flash latest firmware and Proxmox will use the simpler mpt3sas driver. I run it in production with both ZFS and Ceph with no issues.
-
Jjdancer replied to the thread proxmox install& best practice.Best practice is to separate OS and data storage. So, install OS on small boot drives mirrored. I use ZFS RAID-1. Then rest of drives for VMs/data. Your future self will thank you.

Jjdancer replied to the thread Backup Server compatibility between versions..Just used PBS 3 to backup to PVE 9 hosts. No issues. Once the backup was done, clean installed PBS 4.
